DAVID` R. OVERMAN, OF ST. LOUIS, MISSOURI.

. ELECTROIVIEDICAL APPLIANCE.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 10,1907. Serial No. 351.580.

T0 LZZ whom, 25 may concern.-

Beit known that I, DAVID R. OvERMAN, a citizen of the United States, andaresident of the city of St. Louis and State of Missouri, have inventeda new and useful Improvement in Electromedical Appliances, of which thefollowing is a specication.

This invention relates to electro-medical appliances and particularly topads used as an adjunct to the medical treatment for liver and kidneydiseases, andA constitutional and nervous ailments resulting from suchdiseases.

It has for its principal objects to produce a combined medical andelectro-galvanic pad which is simple and effective, which can be easilycleaned and medicated; and to attain certain advantages hereinafter setforth.

The invention consists in the parts and in the arrangements andcombinations of parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification andwherein like symbols refer to like parts wherever they occur, Figure lis a view showing the manner in which the pad is usually applied, Fig. 2is a view of the pad showing the cushion side; Fig. 3 is a view, of theopposite side with portions removed to show the interior arrangementsand, Fig. 4 is a section on line 4-4 of Fig. 2, on an enlarged scale.

The pad comprises a cushion 1, preferably lambskin 2 prepared with thewool thereon. A backing-sheet 3, preferably soft skin or leather, isstitched or otherwise secured at its side and bottom edges to thelambskin 2, thus forming a pocket having its opening at the top. Withinthis pocket is provided a lining of material which is impervious tomoisture. Preferably, this lining is composed of two sheets or layers ofmaterial. The outer sheet 4 is waterproof sheeting and the inner sheet 5is rubber. Obviously, however, the lining may be made of any othersuitable material.

A plurality of Zinc disks 6 are secured within the pocket. These disksare provided with central apertures to receive headed copper rivets 7The rivets are passed through the lambskin 2 through the interposedpocket sheets 4 and 5; and through the apertured disks 6 and upset upona washer 8. Oopper disks 9 are placed adjacent to the Zinc disks 6 butspaced therefrom. These copper disks are fastened in position withcopper rivets in amanner like the Zinc disks. The number ofdisks, bothcopper and zinc, depends upon the required strength of the battery. Aremovable absorbent cloth or pad 10 is placed in the pocket in contactwith the disks 6 and 9. When the pad is saturated with vinegar oracidulated water an electro# galvanic action is set up through the Zincdisks and copper disks and rivets.

The device may be provided with a securing belt or straps l 1 as shownin the drawings, or, if desired, it may be extended into a completegirdle or belt. v

The pad is especially designed as an adjunct in the local treatment orapplication to the sacral plexus of nerves belonging to the greatsympathetic system through which the cause of the diseases hereinenumerated is reached. Its medicinal value is derived from themedicaments with which it is medicated. The wool is first combed andbrushed until it is as fine and soft as fur, and then medicatedaccording to a plan to suit each individual case. The medications arerenewed daily or at such intervals as necessary. The pad is applied overthe regions of the kidneys, liver, and the said Hsacral plexus.

By constant warmth and gentle friction from the wool, aided by thegalvanism, the curative effect of the medications is very muchaccelerated. That the pad possesses peculiar intrinsic qualitiesinherent in the lambswool, and that the galvanism becomes effectivethrough the lambswool when it has been medicated and becomes moistenedfrom the exhalation from the body, has been demonstrated beyond doubt.

Obviously` other material may be substituted for the lambswool and thedevice is capable of considerable modiiication within 9 the scope of theinvention. Therefore, I do not wish to be limited to the specificconstruction and arrangement shown and described.

What I claim as my invention and desire to secure by Letters Patent is:

l. A pad comprising a cushion of soft leather prepared with woolthereon, a pocket attached to said leather, said pocket having a liningof moisture-proof material, and an electro-galvanic battery within saidpocket, said battery having terminals extending into the wool of saidcushion.

2. A pad comprising a soft fibrous cushion, a pocket of materialimpervious to moisture,

tends into said fibrous cushion, and an absorbent pad in said pocket inContact with said zinc and copper disks.

In testimony whereof I have signed my naine to this speciiication in thepresence of two subscribing Witnesses this 2nd day of January, 1907, atSt. Louis, Mo.
